I second this, I'm also a big fan of Stillwell's Schwa Olga you can download for free and you have nag screen each time you load it up but I would always say pay for it because it's a great product and Stillwell deserve your cash. My entire recording setup seems to be based around Stillwell plugins these days.

I've noticed that whilst many people praise u-He Diva (and it looks like a great product), there is usually a caveat about resources. Apparently it is quite cpu-hungry - which may be a factor when deciding. It's still on my list of things to check out, but not quite as high as it was...

Yesterday, Chevvers and I were mixing and he introduced me to Diva. Lets just say, apart from Falcon for my more evolving and complex sounds Diva has taken over all my synth duties for all mix projects. Truly well designed and thought out and I don't care about the cpu hog: I believe they have updated the code threading for better offline processing.
